Summary

Thoroughly revised and updated edition of this in-depth discussion of both video compression and communication technologySince the publication of Wireless Video Communications five years ago, the area of video compression and wireless transceivers has evolved even further. This new edition addresses a range of recent developments in these areas, giving cognizance also to the associated transmission aspects and issues of error resilience. In this revision of Wireless Video Communications, substantial new material has been added on areas such as H.264 and MPEG4 coding. Covering compression issues, error resilience, coding delay, implementational complexity and bitrate, the book also gives an historical perspective to video communication. Includes brand new, previously unpublished information on advances in the field of video compression and communications. Introduces substantial new material on H.264 and MPEG4 coding and their error resilience and transceivers. Illustrates the expected performance of various video codecs in the context of integrated wireless transceivers. Covers video compression, channel coding and transmissionPostgraduates and researchers in communication systems, undergraduates and development engineers of video compression applications will all find this a highly informative read.
